DETAILED DESCRIPTION

In order to make the above purposes, features and advantages of the present disclosure more obvious and thorough understand of the subject matter presented herein, the following is a further detailed description of a heating core and an atomizer of the present disclosure in combination with the accompanying drawings and the specific implementation embodiments. It should be understood that specific embodiments described herein are only used to explain the present disclosure, rather than limiting the protection scope of the present disclosure.

Referring to FIGS. 1-14 , an atomizer 1 according to an embodiment of the present disclosure includes a liquid bin 300, a liquid base 400, an air pipe 500 and a base body 800. The base body 800 is received in the liquid base 400, the liquid base 400 connected with a bottom of the liquid bin 300, the air pipe 500 passing through the liquid bin 300. The atomizer 1 further includes a heating core 100, an installation room 420 formed between the base body 800 and the liquid base 400 for receiving the heating core 100 therein. A receiving room 310 is arranged in the liquid bin 300 and configured to receive atomized liquid therein, the liquid base 400 including a liquid inlet 410 connected with both the heating core 100 and the receiving room 310. Since the liquid inlet 410 communicates with both the heating core 100 and the receiving room 310, liquid can be fed from the top of the heating core 100, instead of from a side of a conventional heating core. Such design of the liquid inlet 410 is provided that liquid can be smoothly fed from the top of the heating core 100 under an action of gravity, so that it is no need to wrap cotton for guiding liquid, which not only can reduce a manufacture cost, but also can have a better atomization effect. In this way, under the action of gravity, the liquid can better enter micro-pores of a ceramic substrate 110 for atomization, which can avoid the cotton core from being burnt at a high temperature, and when there is liquid in the receiving room 310, the liquid can always be in contact with the heating core 100, to avoid the heating core 100 from being dry burnt. At the same time, it also avoids a situation that residual liquid in the receiving room 310 causes the taste to become worse and worse with the increase of liquid injection times.

Referring to FIG. 6 and FIG. 7 , the atomizer 1 further includes a sealing holder 200 connected with the liquid bin 300 and the liquid base 400 to cooperatively form the receiving room 310 thereamong, the air pipe 500 extending to the sealing holder 200 and isolated from the receiving room 310, and the sealing holder 200 detachably connected with the liquid bin 300. The sealing holder 200 can be detachably connected with the liquid bin 300 to facilitate liquid injection, and the sealing holder 200 or the air pipe 500 can be connected with a suction nozzle 900 to conveniently use the atomizer 1. In particular, the liquid base 400 and the air pipe 500 can be integrated with each other.

Referring to FIGS. 1-5 , the heating core 100 includes:

-   -   a ceramic substrate 110 including an air vent 111 formed on a         middle thereof and connected to the air pipe 500;     -   a heating element 120 arranged on a first surface 1101 of the         ceramic substrate 110 and including an inner ring 121, a first         extension section 122 and a second extension section 123         respectively extending outward from the inner ring 121 and         symmetrically arranged on the inner ring 121; and wherein a         cross section of the inner ring 121 is a first cross section S₁,         a cross section of the first extension section 122 and a cross         section of the second extension section 123 are equal and taken         as second cross sections S₂, and an area of the first cross         section S₁ is less than that of the second cross section S₂.

The air vent 111 is arranged in the middle of the heating core 100 to connect the air pipe 500 of the atomizer 1 so that generated smoke can pass therethrough, that is, a separate aperture for smoke passing therethrough is provided to avoid a large reduction in the amount of smoke caused by micro-pores blockage. When current flows to the inner ring 121 thereof, because the current will disperse to two half rings that form a parallel effect thereof, heating capacity of the inner ring 121 is lower than that of the first extension section 122 or the second extension section 123. The area of the first cross section 122 of the heating core 100 is less than the area of the second cross section 123 of the heating core 100, so that a resistance of the inner ring 120 that is arranged on the ceramic substrate 110 is less than that of the first extension section 122 or the second extension section 123. As the temperature of the inner ring 121 increases, overall heating capacity of the ceramic substrate 110 tends to be uniform, which can avoid situations that the middle temperature of the conventional ceramic heating core is low and a temperature of an outer ring is high.

It can be understood that main parameters affecting the cross section are a thickness and a width, which can be changed by changing only one parameter or two parameters. Referring to FIG. 3 , if the first cross section S₁=l₁h₁, and the second cross section S₂=l₂h₂, thereby only the thickness can be changed to make l₁=l₂ and h₁<h₂.

Referring to FIG. 1 and FIG. 2 , an end of the first extension section 122 away from the inner ring 121 is provided with a first pin portion 1223, a first pin 130 passing through the first pin portion 1223 to form on the ceramic substrate 110, and electrically connected with the first pin portion 1223; the second extension section 123 includes a second pin portion 1233 formed at an end thereof away from the inner ring 121, a second pin 140 passing through the second pin portion 1233 to form on the ceramic substrate 110, and electrically connected with the second pin portion 1233. It can be understood that one of the first pin 130 and the second pin 140 is a positive pole, and the other of the first pin 130 and the second pin 140 is a negative pole. In particular, the first pin 130 and the second pin 140 are directly integrated with the ceramic substrate 110, which has strong stability and can avoid that the first pin 130 and the second pin 140 separate from the heating element 120.

In an embodiment of the present disclosure, all of the first pin 130, the second pin 140 and the heating element 120 are placed in a mold, and then ceramic slurry is injected into the mold, and finally are co sintered to be molded.

Referring to FIG. 1 and FIG. 3 , the first extension section 122 further includes a plurality of first arcs 1221, and a plurality of first connecting portions 1222 connected with two adjacent first arcs 1221 or connected between one of the plurality of first arcs 1221 and the inner ring 121. The second extension section 123 further includes a plurality of second arcs 1231, and a plurality of second connecting portions 1232 connected with two adjacent second arcs 1231 or connected between one of the plurality of second arcs 1231 and the inner ring 121. In particular, both the first arc 1221 and the second arc 1231 are concentric with the inner ring 121. The two adjacent first arcs 1221 generally extend in two opposite directions, respectively, that is, one extends along a clockwise direction and the other extends along a counterclockwise direction, which is the same as the second arc 1231. Since the first extension section 122 includes the first arc 1221 and the second extension section 123 includes the second arc 1231, and the ceramic substrate 110 is a cylinder with an arc-shaped surface, so that the heating core 100 is more uniform heated.

Referring to FIG. 1 and FIG. 3 , the heating element 120 includes a fixing portion 150 connected with the ceramic substrate 110 to press the heating element 120 on the ceramic substrate 110. The fixing portion 150 is provided to prevent the heating element 120 from being warped due to high-temperature deformation, so that the heating element 120 can always cling to the ceramic substrate 110 to avoid the heating element 120 from being separated from the ceramic substrate 110. All of the fixing portion 150, the heating element 120 and the ceramic substrate 110 are generally integrated by high-temperature sintering. The fixing portion 150 is generally arranged on the first extension section 122 and the second extension section 123, a shape of the fixing portion 150 can be a cylinder, a hemisphere or a cube, specifically, it can be arranged according to actual requirements, the fixing portion 150 is preferably a long block shape. In particular, referring to FIG. 3 , the fixing portion 150 can extend radially to press a plurality of segments of the first arc 1221, the second arc 1231 and/or the inner ring 121 at one time.

Referring to FIG. 2 , the ceramic substrate 110 includes a second surface 1102 opposite to the first surface 1101 and the heating element 120, and a plurality of oil storage tanks 112 extending from the second surface 1102 to the first surface 1101, so that liquid can enter the plurality of oil storage tanks 112 under the action of gravity. The plurality of oil storage tanks 112 is provided to increase a contact surface between the liquid and the ceramic substrate 110, facilitate the liquid to penetrate into the micro-pores of the ceramic substrate 110, and improve the amount of smoke. At the same time, the plurality of oil storage tanks 112 can accommodate part of the liquid, and also help to prevent the heating core 100 from being dry burned. The plurality of oil storage tanks 112 is generally arranged symmetrically or in an array surrounding the air vent 111, and the number of oil storage tanks 112 is generally two-four. Other numbers can also be set according to actual requirements. In particular, an annular oil storage tank 112 can also be set, and a plurality of turns can be set according to actual requirements. That is, liquid can be fed from the top of the heating core 100, instead of from the side of the conventional heating core, so that it is no need to wrap cotton for guiding liquid, which not only can reduce a manufacture cost, but also have a better atomization effect, and avoid the heating core 100 from being dry burnt.

It can be understood that the heating element 120 is arranged on the ceramic substrate 110 can be implemented by a ready-made process, which will not be repeated here, and it is not a focus of the present disclosure. For example, it can be formed by high-temperature co sintering.

Referring to FIG. 6 and FIG. 7 , an electrode pole 821 is arranged on a bottom of the base body 800 and connected with the first pin 130, and the second pin 140 connected with the base body 800 to form a circuit through the inner ring 121.

The condensation seat 700 includes a first hole 720 and a second hole 730, the first pin 130 of the heating core 100 passing through the first hole 720 to connect with the base body 800, and the second pin 140 of the heating core 100 passing through the second hole 730 to connect with the electrode pole 821. The condensation seat 700 is provided to absorb condensate liquid, and a flow direction of the airflow can be changed through the air vent 111.

Referring to FIG. 12 , the airway 710 of the condensation seat 700 faces the heating element 120, so that the airflow during air intake is blown to the heating element 120 and then enters the air vent 111. The airflow flows to the heating element 120 to be cooled down, which can take away part of the temperature of the heating element 120 and avoid excessive temperature of the heating element 120.

Preferably, the condensation seat 700 is made of a material with the micro-pores, and is preferably made of ceramic or other similar materials, so as to conveniently adsorb condensate liquid and avoid leakage of condensate liquid from the base body 800, so that the electrode pole 821 is influenced to be used.

Referring to FIGS. 6-7 and FIG. 11 , the atomizer 1 further includes a sealing seat 600 made of flexible material and hermetically connected with the liquid base 400 and the heating core 100, so that the receiving room 310 is hermetically isolated from the air pipe 500 and the air vent 111. The sealing seat 600 includes a passageway 610 connected with the liquid inlet 410, and a blowhole 620 connected with the air vent 111. The sealing seat 600 mainly plays a sealing role to avoid liquid leakage from a peripheral wall of the heating core 100 and the air vent 111 to the base body 800 or the condensation seat 700, resulting in liquid leakage. It can be understood that the sealing seat 600 isolates the air vent 111 of the heating core 100 from the oil storage tank 112 to avoid liquid leakage caused by liquid directly entering into the air vent 111.

During installation, the insulating sleeve 822 is placed in the electrode hole 820 of the base body 800, and then the electrode pole 821 is placed; the sealing seat 600 is sleeved on the heating core 100; the first pin 130 passing through the first hole 720, and the second pin 140 passing through the second hole 730, and then the first pin 130 is connected with the base body 800 and the second pin 140 is connected with the electrode pole 821. The air pipe 500, the liquid base 400 and the liquid bin 300 that are integrated are connected with each other, the base body 800 is connected with the liquid base 400, and then, liquid is injected into the receiving room 310, the sealing holder 200 is sealed on the above assembly, and finally the suction nozzle 900 is connected with the above assembly, thereby the assembly of the atomizer 1 is completed. At this time, the atomizer 1 can be connected with a corresponding power supply control device to be used.

When the atomizer 1 is used, the airflow enters from the air inlet 810 of the base body 800, flows to the heating element 120 through the airway 710 of the condensation seat 700, then enters the blowhole 620 of the sealing seat 600 from the air vent 111 of the ceramic substrate 110, then passes through the air pipe 500 that is integrated with the liquid base 400, and finally flows out of the suction nozzle 900. That is, outer cold air flows to the heating element 120 through the air inlet 810 and the airway 710, and then flows out through the air vent 111 and the blowhole 620. In the whole process, the heat generated by the heating element 120 is taken away by the airflow in and out, so as to cool the heating p element 120. At the same time, the smoke generated by the heating core 100 enters the air vent 111 through the micro-pores of the ceramic substrate 110, and the smoke together with the airflow flows out of the suction nozzle 900. That is, the smoke generated by the heating core 100 flows out through the micro-pores of the ceramic substrate 110, the air vent 111 and the suction nozzle 900, so as to obtain a better taste.
